Smoke explosion refers to a smoke cloud formed by mixing combustible smoke and air in a certain space. Under the action of an ignition source, the mixture of smoke and air burns rapidly and causes a sharp rise in the temperature of the chemical reaction. Dust explosions mostly occur in aluminum powder, zinc powder, aluminum processing grinding powder, various plastic powders, organic synthetic drug intermediates, wheat flour, powdered sugar, wood chips, dyes, bakelite ash, milk powder, tea powder, smoke powder, coal powder , Plant fiber and other production and processing sites. Dust collector explosion-proof

In the formation of dust explosions, combustible substances, air and ignition sources are the three basic conditions for the occurrence of an explosion, that is, the three elements of an explosion.

Will the dust explode? Explosion-proof dust collector is mainly used for preliminary identification of dust collector dust collector samples, and on-site judgment of the explosiveness of dust collector dust collector.

Minimum ignition energy test: Determine whether the electrical equipment discharge can ignite explosive dust and air mixture, use the minimum ignition energy to evaluate the corresponding fire hazard caused by electrical or electrostatic discharge, and finally determine whether the electrical equipment is suitable for installation in the presence of explosive dust The place.

Dust collector explosion-proof detection of the minimum ignition temperature of smoke and dust: control the temperature of the hot surface of the smoke and dust, prevent the smoke and dust from sparking in the smoke and dust, and provide a basis for the selection of smoke and dust Explosion-proof electrical equipment.

Passing the minimum ignition temperature test can provide the following information:

Ignition sensitivity caused by hot surfaces that may exist in the dryer, overheating of bearings and other mechanical parts, ignition sensitivity caused by friction, and the maximum allowable external surface temperature of electrical equipment.
